753 guy 2 #1 Posted October 27, 2020 Does any one know what 8 speed transmission will fit into a 753, if any. Thank you. Share this post Link to post Share on other sites
ebinmaine 68,885 #2 Posted October 27, 2020 @pullstart Kevin has put an 8 in a round hood. He'll chime in at some point. I'm kind of thinking most any 8 will go in there but your linkage might be easier to adapt if you can find a SIX and then you would also end up with Limited Slip Differential.

71_Bronco 1,072 #3 Posted October 27, 2020 I'm pretty sure just about any 8-speed can be put in, but some will take more work than others. If you look for a Unidrive 5060, then it will be the easiest to swap in. It has the brake drum / brake band in the same spot as your 3-speed, and has the LSD differential as Eric mentioned. The later 8-speeds have a different brake set-up, and will require some modifications. Also, some of the later ones have a dipstick fill port on the top that will have to be modified or removed. I put a 5060 into my '68 Commando 8 (had a 3-speed) and it bolted right in, no modification to the brake arrangement. 1 Share this post Link to post Share on other sites
Pullstart 63,203 #4 Posted October 27, 2020 I put a C-101 8 speed in my 502 “Putt Putt”. I never did complete the parking brake, but I generally keep it on a flat area anyway. I agree with Eric, a 6 speed would be a direct swap, shy of relieving the tool box for the hi/lo shifter Share this post Link to post Share on other sites
Chris G 3,296 #5 Posted October 28, 2020 (edited) Im building a custom right now, that has a 753 frame and i used a workhorse gt 1100 6 speed transaxle and i used the front axle as well. Also i ended up using 701 sheet metal and the last pic gives a idea of the mods made to tool box for the dipstick and u can get a general for were a hole was drilled for the hi lo shifter.

ebinmaine 68,885 #6 Posted October 28, 2020 @Chris G Super cool ride. Are the rear sneakers OTRs? 1 Share this post Link to post Share on other sites
ri702bill 8,562 #7 Posted October 28, 2020 I put the 8 speed Unidrive from a 1979 C81 in my 854 a few years back. As discussed above, the dipstick and tube needed to be shortened due to the fixed seat. I had to remove about 4 inches as I recall. Used a brake rod from a Raider 10 - hooked right up. The picture below is while the project was ongoing - I later shortened the Hi-Low lever a bit. Bill 1 1 Share this post Link to post Share on other sites
Pullstart 63,203 #8 Posted October 28, 2020 Yep, forgot about the dipstick tube! I shortened mine as well. Share this post Link to post Share on other sites
Chris G 3,296 #9 Posted October 28, 2020 @ebinmaine i do believe they are lawn trac otr. I know they definitely dig in pretty good for tugging stuff around. 1 1 Share this post Link to post Share on other sites

Pullstart 63,203 #12 Posted October 29, 2020 I know for auto tires, “siping” the lugs is commonplace for better winter grip. It is pretty much a ton of tiny razor blade cuts in the lugs of the tire to make each new section grip the ice and snow better. I’d love to see what siping some of my new Interco Interforce tires would do for wintertime use, but feel like the solid heavy lug is required for plowing fields even more. 2 Share this post Link to post Share on other sites

I love that shade of green on that tractor, I'm not a huge green fan but the shade and the wear Mark's just make it look that much tougher! 1 1 Share this post Link to post Share on other sites

That would be an interesting experiment. I know that dirt oval track racers sipe their tires for better grip, but then again they are on hard pack clay. I'd have a hard time cutting up new tires to try this out though. 2 Share this post Link to post Share on other sites

753 guy 2 #16 Posted October 31, 2020 I've located 91-11B801, 8 speed transmission, does any one know if this will bolt right or will it need modifications. It comes from C-111 tractor. The good thing about this one is at least its not to far from home. Thank you, Mike 1 Share this post Link to post Share on other sites

You'll need to drill a hole in the toolbox. See the first few posts and maybe the other folks can answer more specifically. Share this post Link to post Share on other sites

Greatly appreciated. That's what we're all here for. Share and share alike. Wheelhorse tractors for sure and also about many many other things. Keep asking questions. Jump in to the build. You'll find a thousand more queries and every one will have an answer. Best part of the adventure. 1 Share this post Link to post Share on other sites

Greatly appreciated. You’ll surely know more when you start turning the wrenches! I believe most of us here are hands on learners. You might read about a process (or me, dream at night about the next step in a build/project over and over all night) but nothing compares to rolling up your sleeves and diving in!
